Need Campground Near Calgary

I pretty much have the itinerary laid out for our spring trip back to Alaska - everything except a campground in or around Calgary. We will be coming up Canada 2 from Lethbridge to Edmonton and Calgary is about where we will be when it's time to make camp.

All of the campgrounds I've found in Woodall's and the RV Park Reviews's website are way off Highway 2.

If anyone knows of a campground on Canada 2 that will be open in April, please post back or send me a private message.
